Recombinant proteins have revolutionized multiple industries, from healthcare to biotechnology. Produced through genetically engineered expression systems, these proteins offer distinct advantages over their naturally sourced counterparts. With high activity, purity, batch – to – batch consistency, and the ability to optimize various characteristics, they have become the cornerstone of many applications, including biopharmaceuticals, industrial enzymes, and diagnostic proteins.

The Production Processes at Hzymes

Fermentation Process: The Foundation of Protein Production

The fermentation process at Hzymes begins with small – scale shaking flask cultivation. This crucial step allows experts to determine the optimal microbial growth conditions before moving to larger – scale fermentation tanks. During high – density fermentation, different cultivation methods such as batch fermentation, fed – batch, or continuous fermentation are employed. These methods are carefully selected and optimized to enhance fermentation density while maintaining a balance between cost and efficiency.

Key parameters like pH, temperature, dissolved oxygen, carbon dioxide levels, aeration, agitation, and the resulting shear forces are closely monitored and controlled. Hzymes’ equipment scaling is well – structured, starting with shaking flasks for strain recovery, 5L fermenters for preliminary parameter testing, and 50L fermenters for industrial pre – scale verification. For specific projects, such as those involving E. coli and yeast expression systems, Hzymes has successfully achieved high – density fermentation using 500L fermenters. They offer process development and scale – up production services, optimizing key parameters to ensure a stable fermentation process.

Purification Process: Ensuring High – Quality Proteins

After fermentation, the purification process is essential to obtain high – purity and high – activity recombinant proteins. Hzymes utilizes several chromatography techniques:

• Affinity Chromatography (AC): 

This method is commonly used for purifying His – tagged proteins. It can achieve over 85% purity in a single step and is widely applied in the purification of antigens and diagnostic enzymes.

• Size Exclusion Chromatography (SEC): 

SEC separates molecules based on their size, with larger molecules eluting first and smaller ones later. While it has a simple operation, its sample capacity is limited, and it comes with higher costs due to equipment requirements.

• Ion Exchange Chromatography (IEX): 

IEX separates molecules through reversible charge interactions. By adjusting the buffer pH or ionic strength, the binding and elution of proteins can be precisely controlled. This technique is widely used for purifying proteins and nucleic acids.

• Hydrophobic Interaction Chromatography (HIC): 

HIC takes advantage of the hydrophobic differences between proteins for separation. By gradually reducing the salt concentration, proteins are sequentially released based on their hydrophobicity.

HZYMES provides purification platforms of various scales, facilitating quick process transfer and scale – up. This ensures the production of high – activity proteins that meet strict quality standards. In a case study for Project C (E. coli), Hzymes developed a special purification protocol that achieved an impressive 99.9% purity, with endotoxin levels <10 EU/mg, an expression level of 20 mg/g wet biomass, and batch yields exceeding hundreds of grams.

Freeze – Drying Process: Preserving Protein Integrity

Recombinant protein liquid formulations are often unstable during storage and transportation, especially under low – temperature conditions. They may aggregate or denature, leading to a loss of functionality. Hzymes’ freeze – drying process addresses this issue by improving protein stability. This not only safeguards the quality of the proteins but also reduces storage and transportation costs. Hzymes offers freeze – drying platforms of various scales and utilizes advanced formulation development techniques. Their automated systems ensure aseptic production, maintaining the highest standards of quality.

Hzymes’ CMO Service Workflow

HZYMES offers two types of CMO service workflows to meet different client needs:
